Syntra Functions & Schedules

Edge functions

Syntra runs edge functions on a Deno runtime. Write TypeScript/JavaScript functions that deploy and execute on demand.

Create and deploy

1. functions_create — create a function with source code
2. functions_deploy — deploy to the edge runtime
3. functions_invoke — call by slug

Function lifecycle

functions_create → functions_deploy → functions_invoke
                         ↑
                  functions_update → functions_deploy

Create a function

{
  "name": "Hello World",
  "slug": "hello-world",
  "code": "export default async function handler(req: Request): Promise<Response> {\n  const body = await req.json().catch(() => ({}));\n  return new Response(JSON.stringify({ message: 'Hello!', input: body }), {\n    headers: { 'Content-Type': 'application/json' }\n  });\n}",
  "description": "A simple hello world function"
}

Function management

• functions_list — list all functions with optional status filter and pagination
• functions_get / functions_get_by_slug — get function details
• functions_update — update code, name, slug, description, or status
• functions_delete — delete a function
• functions_list_deployments — view deployment history

Invoke a function

{
  "slug": "hello-world",
  "body": { "name": "Claude" },
  "headers": { "X-Custom-Header": "value" }
}

Scheduled jobs (cron)

Run functions on a schedule using cron expressions.

Create a scheduled job

{
  "name": "Daily cleanup",
  "cron_schedule": "0 3 * * *",
  "function_url": "http://localhost:7133/functions/cleanup",
  "http_method": "POST",
  "body": { "older_than_days": 30 },
  "is_active": true
}

Cron expressions

Expression	Schedule
* * * * *	Every minute
0 * * * *	Every hour
0 0 * * *	Daily at midnight
0 3 * * *	Daily at 3 AM
0 0 * * 1	Every Monday
0 0 1 * *	First of each month
*/15 * * * *	Every 15 minutes

Format: minute hour day-of-month month day-of-week

Job management

• schedules_list_jobs — list all jobs
• schedules_get_job — get job details
• schedules_update_job — update schedule, URL, or body
• schedules_delete_job — delete a job
• schedules_toggle_active — enable/disable without deleting
• schedules_list_job_logs — view execution history with status and response

Common patterns

Periodic data cleanup:

{ "name": "Purge old logs", "cron_schedule": "0 2 * * *", "function_url": "http://localhost:7133/functions/purge-logs", "http_method": "POST" }

Scheduled report:

{ "name": "Weekly report", "cron_schedule": "0 9 * * 1", "function_url": "http://localhost:7133/functions/send-report", "http_method": "POST" }

Health ping:

{ "name": "Health check", "cron_schedule": "*/5 * * * *", "function_url": "http://localhost:7130/api/health", "http_method": "GET" }
